Mr. Krabbs wants to make Bikini Bottoms a nicer place to live. He has created a new sauce that he thinks will reduce the production of body gas associated with eating crabby patties from the Krusty Krab. He recruits 100 customers with a history of gas problems. He has 50 of them (Group A) eat crabby patties with the new sauce. The other 50 (Group B) eat crabby patties with the sauce that looks just like new sauce but is really just a mixture of mayonnaise and food coloring. Both groups were told that they were getting the sauce that would reduce gas production. Two hours after eating the crabby patties, 30 customers in group A reported having fewer gas problems and 8 customers in group B reported having fewer gas problems.
Which people are in the control group?
Correct Answer
B. Group B
Explanation
BC group B had Mayo + green that looked like the sauce- not the real thing.

Based on this information, baking soda is a ____________.
Correct Answer
base
Base
Explanation
Baking soda is a base because its pH level increases as the amount of baking soda increases. The pH levels consistently increase from 9.3 to 9.7 as the amount of baking soda increases from 9g to 13g. This indicates that baking soda has a higher concentration of hydroxide ions, which is characteristic of a base.

What is the beginning or the building up of this cycle?
Correct Answer
C. Lightning and Nitrifying bacteria
Explanation
The beginning or the building up of this cycle is lightning and nitrifying bacteria. Lightning provides the energy to convert atmospheric nitrogen gas into a usable form called nitrate. Nitrifying bacteria then convert the nitrate into nitrite and then into nitrate, which can be taken up by plants. This starts the cycle of nitrogen being passed from plants to animals and back to the environment through waste and decomposition.
13.
What is the name of this cycle ?
Correct Answer
C. Nitrogen cycle
Explanation
The given question is asking for the name of a cycle. The options provided are Water cycle, Carbon cycle, and Nitrogen cycle. The correct answer is Nitrogen cycle. The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms in the environment. It involves several steps including nitrogen fixation, nitrification, assimilation, ammonification, and denitrification. This cycle is important for the availability of nitrogen to living organisms and plays a crucial role in maintaining the balance of nitrogen in ecosystems.
